i am not sure what my ph of my soil is but how do i raise it?

Note: Be sure the nitrogen or first of the three numbers is zero or as low as possible. Imperial Clover is a legume and produces its own nitrogen. If nitrogen is added it will only promote weed and grass competition.

this is what it says so i dont know what lime to use that doesnt have nitrogen

This should answer your question(s).
